* ath9k: Fix bug in TX DMA terminationSujith2009-01-30
| | | | | | | | | Removing the module was slow because ath9k_hw_stopdma() was looping for a long time quantum. Use reasonable values now to fix this issue. Signed-off-by: Sujith <Sujith.Manoharan@atheros.com> Signed-off-by: John W. Linville <linville@tuxdriver.com>
* ath9k: Setup short preamble properly in rate registrationSujith2009-01-30
| | | | | | | | | This patch fixes an issue where hw_value_short was not being filled with the proper ratecode during rate registration, but was being used in the RX path for decoding the packet rate.

* ath9k: Fix station access in aggregation completionSujith2009-01-30
| | | | | | | | | | The ieee80211_sta pointer in the SKB's TX control info area is not guaranteed to be valid after returning from the tx() callback. Use ieee80211_find_sta() instead and return early if the station is no longer present. Signed-off-by: Sujith <Sujith.Manoharan@atheros.com> Signed-off-by: John W. Linville <linville@tuxdriver.com>

* ath9k: Handle chainmask for A9280Sujith2009-01-30
| | | | | | | | | The default chainmask for AR9280 is 3, so handle that when setting the supported MCS rates. Also, check for the HW supported chainmask when choosing single/dual stream. Signed-off-by: Sujith <Sujith.Manoharan@atheros.com> Signed-off-by: John W. Linville <linville@tuxdriver.com>
* ath9k: remove useless ath9k driver version informationLuis R. Rodriguez2009-01-29
| | | | | | | | | | Versioning for ath9k is pointless we have kept it at 0.1 since the initial release so its meaningless. We put more emphasis on kernel release or dated wireless-testing master tag as per John's tagging. Signed-off-by: Luis R. Rodriguez <lrodriguez@atheros.com> Signed-off-by: John W.

* ath9k: simplify regulatory codeLuis R. Rodriguez2009-01-29
| | | | | | | | | | | | | | | | | | | | Now that cfg80211 has its own regulatory infrastructure we can condense ath9k's regulatory code considerably. We only keep data we need to provide our own regulatory_hint(), reg_notifier() and information necessary for calibration. Atheros hardware supports 12 world regulatory domains, since these are custom we apply them through the the new wiphy_apply_custom_regulatory(). Although we have 12 we can consolidate these into 5 structures based on frequency and apply a different set of flags that differentiate them on a case by case basis through the reg_notifier(). If CRDA is not found our own custom world regulatory domain is applied, this is identical to cfg80211's except we enable passive scan on most frequencies. Signed-off-by: Luis R.

* ath9k: remove superfluous check on changing channelLuis R. Rodriguez2009-01-29
| | | | | | | | | | | | | | | | When we try to change the channel in ath9k its because either the configuration indicates we *have* changed channels or HT configuration has changed. In both cases we want to do a reset. Either way mac80211 will inform us when we want to actually change the channel so trust those calls. Although in the patch it may seem as I am doing more code changes I am not, all I am doing is removing the initial branch conditional and shifting the code to the left. Signed-off-by: Luis R.
